Fusion 360
From Just Solve the File Format Problem
Fusion 360 (also known as Autodesk Fusion) is a 3D design, modeling, and animation program from Autodesk.
Its main file format has a .f3d extension and stores all the items within a 3D model. .f3z files are a compressed version of this. These formats are proprietary to Autodesk.
The Fusion software can also import and export a number of other file types.
